"We must also pay attention to the terms "mulatto" and "colored." The term "mulatto" was originally used to mean the offspring of a "pure African Negro" and a "pure white." Although the root meaning of mulatto, in Spanish, is "hybrid," "mulatto" came to include the children of unions between whites and so-called "mixed Negroes." For example, Booker T. Washington and Frederick Douglass, with slave mothers and white fathers, were referred to as mulattoes. To whatever extent their mothers were part white, these men were more than half white. Douglass was evidently part Indian as well, and he looked it. Washington had reddish hair and gray eyes. At the time of the American Revolution, many of the founding fathers had some very light slaves, including some who appeared to be white. The term "colored" seemed for a time to refer only to mulattoes, especially lighter ones, but later it became a euphemism for darker Negroes, even including unmixed blacks. With widespread racial mixture, "Negro" came to mean any slave or descendant of a slave, no matter how much mixed. Eventually in the United States, the terms mulatto, colored, Negro, black, and African American all came to mean people with any known black African ancestry. Mulattoes are racially mixed, to whatever degree, while the terms black, Negro, African American, and colored include both mulattoes and unmixed blacks. As we shall see, these terms have quite different meanings in other countries"

I think it fix the none loving black folks who think they are not black or African, by classifing them as " African by Descent" People of African descent refer to individuals who originate from the African continent or share biological, cultural, or historical ties to Africa, particularly through global migrations like the Transatlantic Slave Trade.
